My son needs help purchasing a computer for gaming

[Shoe Lace]

Buying a very good or upper mid range video card right now is a pretty bad idea. nvidia's new video card will be coming out in 2 months or so (estimated time, but if it's like the past.. it will happen).

For the games he plays a 7600gt or 7900gs will be more than fine.

Buying a first generation DX10 card with no DX10 games out in addition to performing worse than the better DX9 cards (short of spending a lot of $) seems like a waste of money.
